1) Are there any pros and cons for using a URN for a namespace URI? It seems that most people use URLs but I feel like that adds to the confusion with people expecting that URL to have something there if you go to it with a web browser.
2) If it doesn't matter, is there documentation for the accepted conventions for a schema namespace URN? Mine starts with the following.
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ds="urn:publicid:xmlns:objecteffects-com:schema:dataset"
targetNamespace="urn:publicid:xmlns:objecteffects-com:schema:dataset"
xsi:schemaLocation="
http://www.w3.org/2001/XMLSchemahttp://www.w3.org/2001/XMLSchema.xsd"
elementFormDefault="qualified"
version="1.0">
<xs:element
name="dataset"
type="ds:DatasetType"
/>
Thanks
